Weird thing happend to one of my websites:
In admin panel (Joomla! 3.3.1 Stable - default backend template) after I click an item from the top dropdown menu (Articles for example) and then click anywhere on screen, the menu item disappears.
What happens in the code is that there is dynamically added inline css saying:
display: none
You can see in this video: http://screencast.com/t/EmWxcDiCg0x
Can somebody help me? What can be causing that strange behavior?
EDIT:
Also, when I hover over the view counters in the "popular articles" section in the dashboard, they disappear on mouse out. Strange vanishings can also be seen in few other places.
I think it may have something to do with bootstrap js, but I don't know how to check it.
